IE11 prevents ActiveX from running

Question

Our web browser plugin works fine in IE9 and IE10 but in IE11 the plugin is neither recognized as an add-on or allowed to run. It\'s as if IE11 no longer supports ActiveX.

Answer 1

We started finding some machines with IE 11 not playing video (via flash) after we set the emulation mode of our app (web browser control) to 110001. Adding the meta tag to our htm files worked for us.
